Which battery a Toyota Cavalier takes
Most of the range takes a Japanese-standard JIS battery with thinner posts than a European DIN unit, so a European battery will not clamp correctly even when the dimensions look close. On the Cavalier specifically, which the vehicle database lists across model years 1995 to 2000, the safe approach is to read the label on the battery that is in the car now and match its group size, terminal side and capacity — or to give us the year and let us look it up.
